Programmable DC power sources are an essential tool in product development and production testing of a wide range of electronic devices and systems. In many instances, functional test requires submitting the device-under-test (DUT) to a wide range of operating conditions. In some cases, the DUT draws constant power under variable input conditions. Common examples are DC motor drives and regulated DC/DC supplies. In such circumstances, the ability of the programmable DC source to provide more current at reduced output voltage is valuable. We refer to this ability as “autoranging.” DC supplies without autoranging often require users to use multiple supplies to test the DUT under varying input voltage conditions.
